`CFREENHOUSE.

SPECIFICATION forming part of Letters Patent No. 712,135, dated. October 28, 1902.

' y Application tied May 1, 1902. serien No. 105.486. (No modem T @ZZ whom it may concern:

Be it known that I, CARL ICKEs, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois,

have inventeda new and useful Improvement in Greenhouses, of which the following is a specification.l

My invention relates to greenhouses having a plurality of roof sections or spans; and the xo object of the invention is to provide asimple and at the same time rigid and durable support for the lower ends of the rafters between the side walls.

It is also the object to furnish improved I 5 means for carrying off the water of condensation collecting upon the inside of the roof.

I attain these objects'by the structure illustrated Iin the accompanying drawings, in which- 2o Figure l is an end section-a1 view in elevation, showing a greenhouse embodying my invention. Fig. 2 is a side sectional view of the greenhouse, taken on the line 2 2, Fig. l. Fig. 3 is a detail View showing the construcz 5 tion of the rafter-supports. Fig. 4 is a detail Vview in longitudinal section, taken on the line 44, Fig. 3. Fig. 5 is a fragmentary top view at the lower end of one of the rafters, showing the drip-gutter and adjacent parts. Fig. 6 is a 3o cross-sectional view of a rafter. Fig. 7 is an end sectional View of a greenhouse,showing the use of double supporting-uprights. Fig.v

Sis a detail view of a bracket adapted for said double uprights. i

i 3 5 Similar letters refer to similar parts throughout the several views.

The side walls ct ot are of any suitable construction and form the supports for the rafters at the sides of the building.

4o B B are the ridge-beams to which the upper ends of the rafters c c are attached. Said rafters have drip-conduits o near their lower edge for carrying off water which may condense upon the inside of the roof. Said rafters also have longitudinal ribs c2 and seats os for supporting and retaining the glass D.

A represents the benches, 'which rest upon suitable framework A.

The uprights d are supported from the 5o ground and are attached at their upper extremities to the brackets e. By preference said brackets are provided with bosses e',

which are interiorly threaded' to receive the p threaded upper extremities of said uprights. Said brackets bifurcate at their upper portions to form branches f f for supporting the f2 for permitting the circulation of air beneath i the th rust-piece g, to thereby avoid premature decay. By this construction the thrust-piece. g is firmly held within the bracket e,and lateral motion is prevented. The flanking pieces h extend along the side of the thrust-piece g and are also supported upon the branches f of the bracket. In order to make a tight connection with the thrust-piece g, said Hanking pieces are attached thereto by a tongueand-groove joint. vThe top surface of the thrust-piece is hollowed out slightly in the manner shown in Fig. 3 in order to better carry o rain-water falling upon the roof. The pitch of the flanking pieces h corresponds to the pitch of the roof, and said anking pieces are rabbeted out at theirlower outside edges, so as to receive the drip-gutter i. Said drip-gutter consists, preferably, of galvanized iron, and said ilanking piece h is rabbeted out a sufcient distance to afford a space between the lower end of the rafters and said drip-gutter. Said rafters thereforev do not make contact with said drip-gutter; but said drip-gutter is in position to collect all water which'may be discharged from the drip-conduits in said rafters. An advantage in this construction lies in the fact that the water from the drip conduitsc'f cannot reach to the flanking pieces, and said flanking pieces, which are usually of wood, are

therefore kept dry, anddecayfis avoided. The upper outside edge of each anking piece is also rabbeted out to receive the projecting lower extremity of the rib c2 of the rafter. The glass D also projects into the rabbet in the upper outside edge of the anking piece, so that the water fallingv upon IOO the roof is carried over onto the top of the ianking piece 71..

By referring to Fig. 3 it will be seen that the rain-water falling upon the outside of the roof will be readily carried by the glass D and rafters c over onto the top of the flanking pieces h and that water from said flanking pieces will be carried onto the thrustpiece g. The joints between the pieces h and g are located not in the center and lowest position, but somewhat at the side, so that the water tends to drain away from the joints between said pieces g and h. It will be seen, therefore, that rain-water would be quickly and easily carried off and would not, therefore, have anopportunity to cause the decay l of the parts.

j. Said wires are attached to the brackets c at the apertured lugs m thereon. In order to adjust the tension, I prefer to employ turnbuckles j'in said rods or wires between each span of the building.

I desire to call attention to the advantage in screw-threading the upper ends of the uprights d. The thrust-piece g and flanking pieces h form a gutter for carrying rain-water to the gable ends of the building. In order to make a symmetrical structure, however, it is not desirable to give the roof much pitch or inclination downward toward the gable ends, and as a result if the thrust-piece g sags at any portion of its length water will stand at such point and tend to induce decay. It is of great advantage, therefore, to be able to adjust the height of the thrustpiece, so as to straighten out any pockets or low spots, which might otherwise retain the water. In my construct-ion this adjustment is made possible by the screw-threading of the standards d and brackets e. Said uprights are supported on plates d', set in the foundation, and are free to rotate thereon. By rotating said uprights the brackets c may be raised or lowered sufficiently to straighten out the thrust-piece g, and thereby avoid water-pockets thereon.

In Figs. 7 and 8 an alternative construction of the roof-brackets is shown. In this construction double uprights rise from the ground at some distance apart and near their upper extremities are curved, so as to meet at the roof-brackets o. Said brackets o are similar to the brackets e except that they are provided at the sides with the lugs or projections p for entering into the upper eX- tremities of the uprights n. By employing hollow piping for uprights the upper ends thereof may be slipped over the lugs p and the parts retained in position without additional fastening.

What I claim as new, and desire to secure by Letters Patent, is

In a greenhouse-roof, the combination of a channeled thrust piece extending transversely to the rafters and constituting a drain, flanking pieces at the side of said thrustpiece, rafters as aforesaid abutting said flanking pieces and rabbeted thereinto, a bracket having the branches f at an inclination corresponding to the pitch of the rafters, said branches making contact with said anking pieces and with a portion of said thrust-piece, and said bracket having horizontal shoulders f; and an air-space f2 between said shoulders, substantially as described.

CARL ICKES.
